Be aware you need to pass:

lightctl --user --room # command

Per room session otherwise you'll control all the lighting and annoy other users.

Single-user deployments are fairly common in the gnu lightblub crowd.

Very insecure to run all your light bulbs in the same user context. I use SELightBulb to isolate light bulb actions. If you add PAM and pam-fingerprint you can require a fingerprint to alter lightbulb state for better security. Advise two-factor unless you really don't care for electricity at all.

If electricity isn't your worry, might I suggest installing your lightbulbs in a complete virtual environment?

Instructions unclear; burnt fingerprint on incandescent lightbulb.

Unless you're the father, the you can run sudo lightctl status room to check that bulb.
